Problems solved by technology

[0002] Since the range hoods used in commercial restaurant kitchens are all high-power three-phase fans, whether the range hoods are running normally is very important to the operation of the restaurant. Statistical records to avoid waste of electricity. There is no device and method for early warning of range hood failures in the prior art, resulting in no symptoms before failures, resulting in restaurant operations being helpless against sudden failures, and restaurant operations cannot be smooth. conduct

Abstract

The application discloses an early warning method for a fault of a smoke exhaust ventilator. The method comprises: obtaining actual parameters during the operation of a smoke exhaust ventilator; processing the actual parameters to obtain an average value of the actual parameters; performing difference processing on the average value and preset characteristic data to obtain an early-warning difference value; and according to the early-warning difference value, carrying out fault early-warning prompting. With the method, a fault of a smoke exhaust ventilator can be predicted accurately and alarming is carried out. In addition, the application discloses an early warning system for a fault of a smoke exhaust ventilator.

Description

technical field [0001] The invention relates to the technical field of restaurants, and more specifically, to a method and system for early warning of range hood faults. Background technique [0002] Since the range hoods used in commercial restaurant kitchens are all high-power three-phase fans, whether the range hoods are running normally is very important to the operation of the restaurant. Statistical records to avoid waste of electricity. There is no device and method for early warning of range hood failures in the prior art, resulting in no symptoms before failures, resulting in restaurant operations being helpless against sudden failures, and restaurant operations cannot be smooth. conduct. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method for early warning of range hood failure, which can accurately predict the failure of the range hood and issue an alarm. [0004] To achieve the above objec...
